For Cats with Kidney Disease (CKD) · Coming soon to the App Store

Care for your cat's
kidneys, together.

A CKD diagnosis is overwhelming. RenalPaw makes the daily subQ fluids effortless, tracks the lab numbers that matter against IRIS stages, keeps every caregiver in sync, and turns it all into a clear brief for your vet.

Why RenalPaw
A CKD diagnosis is a lot.
The daily care shouldn't be.
🙀

Subcutaneous fluids, every day

Giving subQ fluids at home is daunting - one hand holds your cat and the line. RenalPaw's fluid log is silent, one-handed, works in the dark, and rotates the injection site for you.

📊

Lab numbers feel like another language

Creatinine, SDMA, phosphorus, IRIS stages - RenalPaw charts them over time with reference bands, so you can see the trend instead of a wall of numbers.

👪

Care is a team sport

Partners, family and pet-sitters all need the same picture. RenalPaw keeps every caregiver in sync through your own private iCloud share.

What RenalPaw does
The clinical layer other
pet apps don't have
Most pet apps are just a med reminder. RenalPaw owns the two things CKD care actually turns on: the daily fluid session, and the lab-and-recheck moment.
SubQ fluids

Fluids, logged in seconds

Pick the volume, confirm the injection site (RenalPaw suggests the next one in the rotation), and start. The whole session logs in under 45 seconds, one-handed and silent, and auto-saves even if a call interrupts.

  • Volume picker with your usual presets
  • Visual injection-site rotation
  • Silent, one-handed, works in the dark

Labs & IRIS

See the trend behind the numbers

Enter each lab panel and RenalPaw plots creatinine, SDMA and phosphorus over time against reference bands, with an IRIS stage estimate - always shown as "confirm with your veterinarian."

  • Creatinine, SDMA & phosphorus trends
  • IRIS stage estimate from your labs
  • Reference bands, not just raw values

Your cat's data stays with you and your iCloud.

RenalPaw has no ads, no analytics and no location tracking. Your logs, labs and photos sync through your own private iCloud (and any caregivers you invite). The monthly AI brief sends a summary to our AI service to write it, then discards it.

FAQ
Good questions,
honest answers
What is IRIS staging? +

IRIS (International Renal Interest Society) staging is the standard vets use to grade feline kidney disease from creatinine, SDMA and other values. RenalPaw shows an estimate from the labs you enter, always to confirm with your vet - never as a diagnosis.

Can my partner or pet-sitter help? +

Yes. With RenalPaw Pro you can share your cat's care with other caregivers through a private iCloud share, so everyone sees the same fluids, meds and labs.

Is RenalPaw veterinary advice? +

No. RenalPaw records your own observations and surfaces them against published reference thresholds. Diagnosis, staging and treatment decisions always belong to your veterinarian.

When does RenalPaw launch? +

Soon - tap "Notify me at launch" and we will email you the day it goes live.
